Equitable IP patent challenged as likely invalid

On September 24, 2017, Unified filed a petition for inter partes review (IPR) against U.S. Patent 7,281,135 owned and asserted by Pen-One Acquisition Group, a subsidiary of Equitable IP, a well-known NPE. The '135 patent, which discloses a pen-based transponder identity verification system, was first asserted earlier this year against Apple and Samsung.
